I useful. Improvements in Stock-Feeders, of

which the following is a specification.

7 My invention relates to stock feeders for automatically feeding stockby the pressure of the animals nose against a portion or thefeedingmechanism. j v

he objects of my invention are; First, to provide device ofthisclass'which is simple and economical of construction, durable,easily installed and does not readily get out of order-;,second, toprovide a device of this class in which, when a certai n quantity offood ,isvin the trough it will automatically stop the feed.

;l /Yith these vand other objects in view as will appear hereinafter, myinvention cons'ists ofcertain novel features of construction,-combination and arrangement of parts as will be hereinafter described indetail and particularly set forth in the appended claims, referencebeing'i had to 'the accompanying drawings and to the characters'ofreference thereon which form apart of this specification; in whichFigure 1, is a sectionalview of my feeder 1 shown in connection with afragmentary portionof a; feed hopper, and Fig. 2, is'a frontelevationalview thereof. 7

Similar characters of referencefrefer to similar parts throughout theseveral views.

The' ybini 1, spiral 2, shaft 3, clutch piece 1, lever 5, link 6, clutchcollar 7 feeding spider 8,- ratchet'wlieelafii, ratchet pawl 10, shield11 and brace 12 constitute the principal parts of my stock feeder.

The bin 1 may be any shape desired and in the lower end is provided anaperture 1 and a cylindrical piece 1 adapted for the spiral 2 to revolvetherein. From the inner edge of this cylindrical piece 1 is a slantingpartition 1 adapted to conduct the feed in said bin to the exposed endof this spiral 2. On the other side of the bin 1 is provided a slantingportion 1 upon which is mounted a bearing 1 adapted for a bearing forone end of the shaft 3. The other end of said shaft is supported bymeans of the brace 12 which acts as a support for said shaft and is pro-Application filed February 1, Seriai fie. 2i4,8

This; spider s is' prfoyided with hiib 8 which is providedwith a plurality of lugs 8 which have faces perpendicular to the face ofsaid hub on one side, and aiigled rates on the'pppesit side. Slidablymounted on the shaft 3" and provided with a key 4, is a clutch piece 4which is rovided withhotehe's conforming to, and adapted to engage withthe lugs 8 on the hub 8 when said clutch piece tisin the proper relativeposition to saidhub iece 8".

This spider8 is covered by means of the shield 11 so that only two or three of thearms are exposed so that the stock in feeding can only press on one ortwo of these arms at a time. Vertically mounted on the shaft 3 on thecrank 3 is a rod 3 which is adapted to agitate the food and keep it frompacking and it is supported by a bracket 3.

Though I have shown and described a particular construction, combinationand arrangement of parts, I do not wish to be limited to thi particularconstruction, combination and arrangement but desire to include in thepurview of my invention, the

combination, construction and arrangementv substantially as set forthclaims.

It is obvious that with this construction, there is provided a stockfeeder in which the animal, by revolving the spider 8 when there is onlya small quantity of food in the troughl will turn the spiral 2causingthe food in the bin to move outwardly through the cylindricalpiece l to the trough; that when sufi'icient quantity of food is in thetrough to press the extended end of the lever 5 upwardly, the clutchpiece 4; will be disengaged from the hub piece 8 and the turning of thespider will then not affect the feeding mechanism; that the device issimple and economical of construction, clurable, easily installed anddoes not readily get out of order.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. In a. stock feeder, the combination of a bin, provided with anaperture and a trough extending therefrom, a cylindrical piece securedin the bottom of said bin, providing communication between said bin andsaid aperture, a spiral revolubly mounted therein, a spider mounted infront of said bin over said trough and means for engaging anddisengaging said spider with said spiral. 2. In a stock feeder, thecombination of a bin provided with an aperture and a trough extendingtherefrom, a cylindrical piece secured in the bottom ofv saidbinproviding communication between said bin and said aperture, a spiralrevolubly mounted therein, a spider mounted in front of said bin oversaid trough, means for engaging and disengaging said spider with saidspiral and in the appended Copies of this patent may be obtained forcured in the bottom of said bin, providing communication between saidbin and said aperture, a spiral revolubly mounted therein, a spidermounted in front of said bin over said trough, means forengaging anddisengaging said spider with said spiral, means for preventing saidspider from turning in one direction and means for covering a portion ofsaid spider.

l. In a stock feeder, the combination of a bin provided with an apertureand a trough extending therefrom, a spiral revolubly mounted in thebottom thereof, a feeding mechanism mounted in front of said bin oversaid trough adjacent the aperture in said bin, gravity actuatedmeans'adapted to connect said; feeding mechanism with said spiral andmeans in connection with said connection means whereby, when there issufficient quantity of food in the trough, said spiral and saidmechanism will disconnect.

5. In a stock feeder, the combination of a bin provided with an apertureand a trough extending therefrom, a spiral revolubly mounted in thebottom thereof, a feeding mechanism mounted in front of said bin oversaid trough adjacent the aperture in said bin, gravity actuated meansadapted to connect said feeding mechanism with said spiral, means inconnection with said connecting means whereby, When there is sufficientquantity of food in the trough, said spiral and said mechanism willdisconnect and means in connection with said spiral for agitating thefood in said bin. I

In testimony whereof, I havehereunto set my hand at Kansas City,Missouri, this 19th day of January, 1918.
